Added a new X configuration option "Interactive", which defaults to enabled, but can be disabled to allow long-running GPU compute programs to run concurrently with X.

Fixed a bug in the VDPAU presentation queue that could cause VDPAU "display preemption" when rendering to tiny or zero-sized windows or pixmaps.

Fixed a bug in VDPAU which prevented use of the overlay presentation

Fixed a bug in VDPAU that prevented the overlay from ever being used if a presentation queue was created while the target window was redirected using the Composite extension when the presentation queue was created.

Reorganized the NVIDIA driver's /proc file system layout to better reflect current needs: /proc/driver/nvidia/cards/0..N has been moved to /proc/driver/nvidia/gpus/0..N/information

Modified colormap updates to no longer be synchronized to vblank. This allows applications to send XStoreColor and XStoreColors requests faster than the screen's refresh rate. This behavior can be controlled by a new NV-CONTROL attribute, NV_CONTROL_SYNC_LUT_UPDATES. By default, LUT updates are not synchronized. This may cause flickering in some applications that use the colormap to perform animation, such as xpilot running on a depth 8 X screen. If you experience flickering, try running nvidia-settings -a [gpu:0]/SynchronousPaletteUpdates=1
